METALLIC CEILING.

SPECIFICATION forming part of Letters Patent No. 406,049, dated July 2,1889.

Application filed November 18, 1888. Serial No. 291,064. (No model.)

T0 66 whom it Huey concern.-

Be it known that I, WILLIAM R. KINNEAR, a citizen of the United States,and a resident of Columbus, in the county of Franklin and State of Ohio,have invented new and useful Improvements in Metallic Ceilings, of whichthe following is a full and exact description, reference being had tothe accompanying drawings, making part of this specification.

This invention relates to improvements in metallic ceilings, and has forits objects to suspend the same directly to the building structure, toso join the panels or parts com posing the ceiling that a portion of theweight of each is suspended by the adjoining panel or part, to providesuspending devices which are easy of manipulation and allow of rapidadjustment, and to disguise the suspending devices by incorporating themin the ornamentation.

111 the drawings, Figure 1. is a plan view of a section of the ceilingwith this invention applied thereto. Fig. 2 is a section of the same,showing the ceiling as applied to a wooden building structure. Fig. 3 isa detail view in section of the ceiling as applied to an iron buildingstructure. Fig. i is a detail the panels composing the ceiling shown inFig. 1 with one form of the suspending devices, the parts beingseparated to show their application. Figs. 5 and (3 are detail views insection of the lapping margins of the said panels joined by alternativeforms of suspending devices. Fig.7 is a detailviewin section showing analternative form of hanging the ceiling to a metallic structure.

The letters X designate the floor-beams of the building structure towhich I apply the ceiling, whether it be a wooden structure, as shown inFig. 2 of the drawings, or metallic, as shown in Fig. The form of panelsdiffers in these two forms only in the hanging-margins, which in themetallic structure I sometimes turn so as to form a hook to engage theflange at the lower edge of the same.

The panels A are stamped or otherwise formed from single metal platesand are provided with the margins 13 and C. The margins B'are providedwith the same moldings that are placed on the margins C. At the outeredge they are provided with the upward extensions B, which rest againstthe structure to which the ceiling is to be applied. At this point thesaid extension is provided with the outwardly-extendin g flange B whichrests firmly against the building structure or beams X thereof. Themargins C rest or lap over the margin B, and are provided at their outeredges with the upward extension 0. This extension, by being turnedupward, makes a joint with the margin B, which is turned away from theeye; and in some constructions, as those shown in Fig. 3 of thedrawings, it forms abrace to hold the flange B on the same panel inposition.

In the majority of instances, when. these ceilings are used, I placearound the room acornice 1), which nailed to the sides of the room andis provided on two adjoining sides with marginal extensionscorresponding to B and O of the panels and having the extensions 13 andG and flange B \Vhen the cornice is omitted, it is substituted by abrad, which is placed in position to receive the margin (E, or theextension 0 of the said margin is bentdown and the panels secured atthose sides by nailing them to the sides of the room through the saidextensions.

In hanging this ceiling the cornice and panels are put up with theflange 13 toward the operator. As each panel is placed in position, itis adjusted by placing the two adjoining margins C over the margins B ofthe adjoining panels. The operator then secures it in position bynailing through the flanges 13 on the two adjoining and exposed sides,and so on until all the panels are thus loosely attached, when thecornice having the extension corresponding to the margin 0 is set inposition, with the said extension lapping the margins 13 of theadjoining panels, and nailed to the sides of the room at the bottomflange. The lapped margins are now secured by means of the suspendingdevices E, F, and G. (Shown in Figs. t, 5, and (3 of the drawings.)

The device E (shown in Fig. 4) consists of a small headed bolt passedthrough the face of the margin 13 with the head resting against theupper or inner surface of the said margin. The head is soldered firmlyto the margin 13, so that in adjusting the next panel it will not bedislodged. The margins 0 are all provided with perforations so disposedas to fit over the threaded shanks of the devices E. WVhen they are soadjusted, the round buttons E are secured on the exposed shank and downagainst the margin 0, drawing it firmly against the margin B andsuspending those sides of the panels to the said margins B of theadjoining panels. The margins are decorated by small bosses, as shown inFig. 1 of the drawings, so that the button, corresponding as it does tothe said bosses, is disguised as one of them and lost in the design. Thedesign and decoration of these bosses may be varied to any extentwithoutinterfering with the construction as described.

The device shown in Fig. 5 consists of an elongated washer or nut F,which is passed crosswise through the margins B bymeans of slots in thesides thereof that are provided. The said nut is provided with athreaded perforation in line with perforations provided in the margins Band C, and which come together when the said margins are lapped. The nutis formed from wroughtiron or any suitable metal that may be turned atthe ends, as shown in the drawings, to hold the nut in position duringthe adjustment of the panels.

\Vhen the panels have been adjusted, as above described, the metalscrews F are passed through the perforations in the lapped margins andmade to engage the threads in the perforation in the nuts F, when it isdriven up until the head of the screw rests against the margin 0 anddraws the same up against the margin 13, and thus supports those sidesof the panels. The faces of the margins are decorated with rosettes F",into the center of which the heads of the screws F sink, and in thedesign of which they are lost, being disguised as part of theornamentation.

The device shown at Fig. 0 is in the form of a key or wedge. It consistsin the hook G with the head G. To receive the hook, the margins areprovided with elongated perforations in line. IVhcn the panels have beenadjusted, these devices are applied by pressing the margins together andpassing the hook G into the perforations and over the margin B until thehead G rests against the margin 0. If the device is not in this positionas securely fastened as desired, small wedges may be driven under theheads until it is so. The shape of thehead, as in the other describeddevices, is formed to harmonize with the decoration of the said margins.

In the drawings, at Fig. 2 is shown a means for hanging the ceiling tometallic building structures, which consists in bending the flange B toform the hooked edge In operation this form of suspension depends uponthe joining of the margins B and O, as by so joining the said marginsthe hooked edges are held firmly in position on the flanges of the beamsX. In this construction, as in the others, the panels are adjusted withthe flanges 13 next the operator, which are turned over the flanges thenin order to make a snug fit, or are turned before beingplaced inposition.

In Fig. 7 is shown a form of hanging the ceiling to a metallic buildingstructure wherein the flanges are omitted at the lower edge of the beamsX. In this case I use the suspending-hook II, (shown in the drawings,)the crook of which I pass over the beam and attach'to the lower end ofthe flanges 13 of the panels. The fastening at the lower end may be ofany suitable description, so I do not confine myself to that particularform shown in the drawings.

WVhen the ceiling is suspended in any'of the ways above described,it iscolored as de sired, and then presents a neat and pleasing appearance.

It is obvious that the forms of the elements of this invention may bevaried indefinitely while accomplishing the same purpose in the sameway. Therefore I do not confine myself to any of the said forms. In Fig.4 of the drawings I have shown by means of the dotted lines Z thesuspending-strips, by means of which the ceiling is suspended from thebuilding structure. The suspending-strip, as shown by the line Z, may beof any shape which will still retain the flange B the extension B, andthe part which passes under or engages the suspending devices. Further,it may be separate and not integrant with the margin B, which may notextend beyond the suspending devices that join thelapped margins of thepanels.

\Vhat I claim is- 1. In a metallic ceiling such as described, thecombination of panels provided at the sides with margins adapted to befitted over the margins of the adjoining panels and having on one ormore sides an extension which is secured to the building structure, andfastenings for securing the fitted margins together, the exposed partsof which are incorporated into the design and ornamentation of the saidpanels, substantially as described.

2. In a metallic ceiling such as described,

the combination of panels provided on thesides with the margins B and O,the extensions B, extending from the said margins B and secured tothebnilding structure, and fastenings to hold the said marg ns together,substantially as described.

3. In ametallic ceiling such as described, the combination of panelsprovided on the sides with margins B and O, the extensions 13, extendingup from the said margins B, hooks engaging the beams of the buildingstructure and attached to the said extensions, and fastenings to holdthe said margins together, substantially as described.

In testimony whereof I have hereunto set my hand this 12th day ofNovember, A. D.
